I weas fortunate enough to see WE WILL ROCK YOU earlier in the year and it was great!! HIGHLY RECCOMMENDED (there's a sci-fi flavour)
As far as Steinman and non-Steinman songs are concerned then yes, a MEAT LOAF musical would be quite easy to write (I could have a look later on). (The only problem would be gettig copyright over the songs, but that might not be too hard). Getting TANZ DER VAMPIRE to the West End (The original version, not the Mikey Boy rubbish) needs to be done
See ya,
Danny
